Abstract

The present invention relates to methods and catalysts for hydrolyzing complex carbohydrates. In an embodiment, the invention includes a process for producing monosaccharides from a complex carbohydrate feedstock including the operations of heating the complex carbohydrate feedstock to a temperature greater than about 150 degrees Celsius and contacting the complex carbohydrate feedstock with a metal oxide catalyst. In an embodiment, the invention includes a method of hydrolyzing complex carbohydrates including the operations of heating the complex carbohydrate feedstock to a temperature greater than about 150 degrees Celsius and passing the complex carbohydrate feedstock through a housing to form a reaction product mixture. In an embodiment, the invention includes a polysaccharide hydrolysis reactor including a reactor housing and a catalyst disposed within the reactor housing. Other embodiments are also described herein.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 889,730, filed Feb. 13, 2007, and U.S. Provisional Application No. 60 / 911,313, filed Apr. 12, 2007, the contents of all of which are herein incorporated by reference in their entirety.FIELD OF THE INVENTION

[0002] The present invention relates to methods and catalysts for breaking down carbohydrates. More specifically, the invention relates to methods and catalysts for hydrolyzing complex carbohydrates.BACKGROUND OF THE INVENTION

[0003] Carbohydrates are fundamentally important molecules to living organisms. Carbohydrates include a group of organic compounds based on the general formula Cx(H2O)y. The group specifically includes monosaccharides, disaccharides, oligosaccharides, polysaccharides (sometimes called “glycans”), and their derivatives. Some carbohydrates serve as a chemical store of energy for living organisms. For example, glucose is a monosaccharide found in fruits, honey, and the blood of many...
